A General and Robust Method for the Preparation of (E)- and (Z)-Stereodefined Fully Substituted Enol Tosylates: Promising Cross-Coupling Partners

A robust method for preparing (E)- and (Z)-stereodefined fully substituted enol tosylates is described. α-Substituted β-keto esters undergo (E)-selective enol tosylations using TsCl-Me2N(CH2)6NMe2 as the reagent (method A, 13 examples; 63-96%) and (Z)-selective enol tosylations using TsCl-TMEDA-LiCl as the reagent (method B, 13 examples; 62-99%). A plausible mechanism for the (E)- and (Z)-enol tosylation selectivity is proposed. A 1H NMR monitoring experiment revealed that TsCl coupled with TMEDA formed a simple N-sulfonylammonium intermediate.

Stereoselective synthesis of new chiral N-tertiary tetrasubstituted β-enamino ester piperidines through an ammonia-catalyzed process

We report here two approaches for the preparation of new N-substituted β-enamino ester piperidines featuring an exocyclic tetrasubstituted double bond, based either on the direct alkylation of piperidine β-enamino esters bearing an exocyclic trisubstitute
